How do I complete our wiki assignment?
Create a digital copy of your page first, then past it on the wiki page. If you are using another document (graph image, digital drawing) please don't make us download it to see it, upload the image to the page instead.
There are two purposes for the wiki. One, to give all students experience and practice using technology to display their ideas. Second, to assist those not present in class to give them a sense and concrete examples of what has happened in class on the day of the lesson. Keep these goals in mind as you check your work.Your page should include all of the following information, and anything else that you would like to improve the appearance of your page.
